Abstract

<P>PROBLEM TO BE SOLVED: To provide a package capable of suppressing leakage of a fluid enclosed in a sealed receptacle even under a reduced pressure and to be manufactured at a low cost. <P>SOLUTION: A bag 12 contains an inner box 11 while the external faces of the box 11 are located at a short distance from inner side faces of a case body 13 (the shape (form and size) of the bag 12 is approximate to an internal shape of the case body 13). Therefore, even if the bag 12 slightly expands, it immediately abuts on the case body 13 to have its expansion controlled, and as a result the change of expansion of the bag 12 can be suppressed to be small even under the reduced pressure. Thus, a drop in atmospheric pressure in the bag 12 is small, and a balance in pressure at an ink delivery port (nozzle forming face 3) formed under a normal pressure is kept even under the reduced pressure. As a result, ink does not leak from the ink delivery port. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a packaging package in which a sealed container in which a fluid is sealed is packed with a packing tool, and a method for packing the sealed container with the packing tool of the packing package.

  2. Description of the Related Art Conventionally, ink jet recording apparatuses that perform recording on a recording medium by discharging ink from a recording head have been widely used. The ink jet recording apparatus is equipped with an ink tank that stores a large amount of ink. The ink in the ink tank is guided to the recording head by a tube, and the ink is supplied to the ink storing portion of the recording head. There is something.

  The recording head discharges the ink stored in the ink storage part from the tip (ink discharge port) of the nozzle communicating with the ink storage part, and performs recording on the recording medium. A plurality of nozzle forming surfaces arranged on the surface of the recording head facing the recording medium.

  In such an ink jet recording apparatus, when the recording head reciprocates in the width direction (main scanning direction) of the recording medium during recording, the tube connected to the recording head moves and the ink in the tube swings. Here, if the oscillation (dynamic pressure) of the ink in the tube is transmitted to the ink stored in the recording head, the ink ejection performance is affected and the print quality is degraded. For this reason, a space (air layer) for absorbing dynamic pressure is provided above the ink storage part of the recording head, and the ink supplied from the tube passes through this air layer to the ink storage part. The recording head is configured to be supplied. According to this, since the ink in the tube and the ink in the ink reservoir are interrupted by the air layer, the dynamic pressure generated by the ink in the tube is absorbed by this air layer and moves to the ink in the ink reservoir. Pressure is not transmitted.

This recording head is distributed in the market as a single consumable part, and at the time of shipment, the initial introduction of ink into the recording head at the start of use is performed smoothly without generating bubbles in the ink. In addition, a storage liquid (preservation liquid) having the same characteristics as the ink excluding ink dyes and pigments is stored inside the recording head (ink storage section). Further, the shipped recording head is packed by a packing body in order to avoid contamination and impact. Such a package is mainly composed of a rubber nozzle protector mounted on a nozzle forming surface (the front end side of the ink discharge port) for sealing the ink discharge port, and a bag-like sheet material for storing the recording head. The recording head is housed and sealed in a sheet material in a state where the ink discharge port is sealed by the nozzle protector and the internal space is sealed (see Patent Document 1).
Japanese Patent Laid-Open No. 11-1046 (FIG. 7 etc.)

  However, the above-mentioned recording head is transported by air depending on the distribution destination, and is exposed to a reduced pressure environment than at the time of manufacture. When the inside of the sheet body that packs the recording head is in a reduced pressure state, the internal pressure in the sealed internal space of the recording head becomes higher than the atmospheric pressure outside the recording head. And when this pressure difference becomes more than predetermined, the air of the space in a nozzle protector (space divided by a nozzle protector and a nozzle formation surface) will leak outside. Along with this air leakage, there is a problem that the liquid stored in the recording head flows out into the space in the nozzle protector through the nozzle, and further leaks out from the space in the nozzle protector.

  In order to prevent liquid from leaking out of the recording head even in a reduced pressure environment, liquid leakage can be avoided by strongly pressing the nozzle protector against the ink discharge port. However, in such a case, an excessive load is applied to the nozzle formation surface. End up. When the nozzle forming surface is strongly and continuously pressed by the nozzle protector, the nozzle forming surface is pushed deeper (in the direction opposite to the ink discharge port) than the initial state (design value). As a result, when the recording head is mounted on the ink jet recording apparatus, the distance between the nozzle forming surface of the recording head and the recording medium becomes longer than the design value, and the landing performance of the ink ejected from the recording head is reduced. There was a problem that.

  In addition, if the recording head is stored (packed) using a sealed container (duralumin case, desiccator, etc.) made of a rigid material such as metal, glass, or ceramic, the pressure in the sealed container can be maintained even in a reduced pressure environment. Therefore, it is possible to eliminate the leakage of fluid from the recording head, but there is a problem that a great cost is required.

  The present invention has been made to solve the above-described problems, and can prevent leakage of the fluid sealed in the sealed container even under a reduced pressure environment and can be manufactured at a low cost.

At the same time, the communication passage is formed by sealing the surplus portion of the first bag body along the direction intersecting the width direction so that the unsealed portion extends to the opening.

  A packaging method for an enclosure according to claim 14 is to pack the enclosure with the packaging container packaging device according to any one of claims 1 to 11, and the first enclosure is opened. An enclosure container storing step for inserting and storing the enclosure container or the enclosure container and the bag body correcting member, and storing the first bag body in the case body partially opened after the enclosure container storing step A first bag body storing step, and after the first bag body storing step, the first bag body is sealed and sealed, and then the opening and closing step of closing the case body is closed. .

  According to the packaging package of the enclosed container according to claim 1, the enclosed container is enclosed and sealed in the first bag body formed of a flexible sheet material. The first bag body that encloses the enclosure is accommodated in the case body. Here, a bag body correction member is disposed on the inner side of the first bag body and on the outer peripheral side of the enclosure, and the first bag body is placed on the inner side surface of the case body by the bag body correction member. The external shape is corrected to a shape approximate to the inner shape of the case body. For this reason, the volume change of the 1st bag body before and behind pressure reduction is suppressed by the correction | amendment by a bag body correction member, and the control by a case body, and the internal pressure change of the 1st bag body under pressure reduction environment can be suppressed. Therefore, even under a reduced pressure environment, the atmospheric pressure, which is the pressure applied to the sealed container in the first bag body, does not change significantly from the environment before the pressure reduction (the original manufacturing environment). In other words, even in a reduced pressure environment, there is an effect that the pressure balance inside and outside the sealed container can be maintained in substantially the same state as in the normal pressure environment in the first bag.

  When the first bag body containing the sealed container expands in a reduced pressure environment, the air pressure in the first bag body decreases in inverse proportion to the expansion amount. That is, the atmospheric pressure, which is a pressure applied to the sealed container from the outside, decreases. Here, since the expansion of the first bag body that is inflated inside the case body is regulated by the rigidity of the case body, the expansion limit thereof is determined based on the inner volume of the case body, that is, each part of the first bag body. Until it comes into contact with the inside. Further, by correcting the outer shape of the first bag body to a shape approximating the inner shape of the case body by the bag body correction member, the first bag body is allowed to reach the expansion limit with a slight volume change (expansion). Therefore, a large pressure drop in the first bag (due to such expansion) can be avoided.

  When a large pressure drop occurs in the first bag body, the pressure of the gas in the sealed container becomes relatively high, and the internal pressure in the sealed container acts in the direction of pushing out the fluid. When an opening for introducing and introducing a fluid is provided in the enclosure, or when a sealing failure occurs, the fluid leaks out of the enclosure due to the pressure of the gas in the enclosure. However, even in a reduced pressure environment, the pressure inside the first bag body can be maintained, and the pressure balance inside and outside the sealed container can be maintained in substantially the same state as in the normal pressure environment, so that no fluid leaks from the sealed container.

  Moreover, since the packing tool should just have the structure for suppressing the expansion | swelling of a 1st bag body, the polyolefin resin which is a versatile resin material, for example, a polyester-type in a 1st bag body, for example Inexpensive general-purpose products such as a resin, a vinyl resin, a polyamide resin, and an acrylic resin can be used. Further, the case body only needs to have a rigidity that restricts the expansion of the first bag body. For example, a thick resin container or a cardboard paper container can be used. Therefore, compared with the case where the enclosure is packed using an expensive metal case, a desiccator, or the like, the packing tool can be configured with an inexpensive material, and the manufacturing cost can be reduced.

  According to the packaging package of the enclosed container according to claim 2, in addition to the effect produced by the packaging package of the enclosed container according to claim 1, in a state where the first bag body is stored in the case body, The first bag body is held at a position away from the inner side surface of the case body via a gap. Moreover, the 2nd bag body which is formed with the sheet | seat material provided with the flexibility and gas is sealed inside is arrange | positioned in the clearance gap between a case body and a 1st bag body. When the external pressure outside the second bag body is a reduced pressure environment lower than the internal pressure inside the second bag body, the expansion of the second bag body in the case body direction is regulated by the case body, The first bag body is pressed by the expansion force of the second bag body, and the expansion of the first bag body in a reduced pressure environment is suppressed. Therefore, even if there is a gap between the first bag body and the case body (even if they are not in direct contact), the expansion of the first bag body is indirectly regulated by the case body via the second bag body. There is an effect that can be done.

  Further, the bag body correcting member is configured to hold the first bag body at a position spaced from the inner side surface of the case body via a gap so that the first bag body is in contact with the inner side surface of the case body. Compared with the case where the structure is held by the above, there is an effect that the dimensional accuracy required for the bag body correction member can be relaxed.

  If the first bag body is brought into close contact with the inner side surface of the case body, that is, if the entire outer surface of the first bag body is held in a position in contact with the inner side surface of the case body by the bag body correction member, the outer shape of the first bag body The shape can be approximated to the inner shape of the case body most, and the expansion of the first bag body can be most suppressed. However, in order to keep the entire outer surface of the first bag body in contact with the inner surface of the case body by the bag body correction member, the dimensional accuracy is as strict as the design value set based on the inner dimension of the case body. It is necessary to process (manufacture) the bag body correction member. If the size of the bag body correction member is not sufficient for the design value, the first bag body cannot be brought into contact with the inner surface of the case body. Conversely, if the bag body correction member exceeds the design value, it cannot be stored in the case body. Because.

  However, the bag body correction member is configured to hold the first bag body at a position separated from the inner side surface of the case body via the gap, and by disposing the second bag body in the generated gap, the bag body The correction member can be securely stored in the case body, and variations in dimensions can be absorbed by the second bag body. Therefore, it is possible to easily manufacture the bag body correction member without requiring strict dimensional control, and sufficiently suppress the expansion of the first bag body even if the bag body correction member manufactured with rough accuracy is used. be able to.

  According to the packaging package of the enclosure according to claim 3, in addition to the effect of the packaging package of the enclosure according to claim 1 or 2, the case body is a box formed in a substantially rectangular parallelepiped, and the bag body correction The member is disposed in the vicinity of the edge of at least two surfaces facing each other across the enclosure, among the bottom surface portion, the side surface portion, and the top surface portion of the case body, and along each of at least one pair of opposite sides of each surface An extended portion is provided. And the external shape of a 1st bag body is correct | amended in the shape approximated to the inner side shape of a case body by constructing a 1st bag body in each extension part.

  Therefore, there is an effect that the outer shape of the first bag body can be easily and easily corrected to a shape approximate to the inner shape of the case body. The shape of the first bag can be a rectangular parallelepiped by having the first bag along the four side surfaces, the bottom surface, and the top surface of the case body. That is, since the first bag body only needs to be held so as to form eight vertices, the bag body correction member is simply placed at the four corners of the rectangular parallelepiped of the case body (the bottom surface portion, the side surface portion, the top surface portion of the case body). Among them, it may be constituted by an extended portion disposed along the pair of opposite sides of each surface in the vicinity of the edge of at least two surfaces facing each other across the enclosure. As such an extended portion, for example, a simple columnar body such as a cylinder or a prism can be used. Four such columnar bodies are arranged at the four corners of a rectangular parallelepiped, and extended portions (bag body correcting members) are provided. Can be formed. For this reason, a bag body correction | amendment member can be set as the simple structure which is easy to manufacture.

  Furthermore, if the bag body correction member having such a simple configuration is used, the volume occupied by the bag body correction member in the first bag body can be reduced. If the volume occupied by the bag body correction member in the first bag body is reduced, a large space can be secured in the first bag body, and the amount of gas sealed in the first bag body should be increased before decompression. Can do. As a result, even if the first bag body is gas permeable, there is an effect that the rate of decrease of the internal pressure of the first bag body under a reduced pressure environment can be made slow.

  In addition, if it is set as the structure which arrange | positions an extending part along two pairs of opposite sides of each surface, the bag body correction member which has an extending part can be made into two frames. According to this, compared with the case where a 1st bag is hold | maintained with four columnar bodies, a holding | maintenance area can be increased and a 1st bag can be favorably supported.

  According to the packaging package of the enclosed container according to claim 4, in addition to the effect exhibited by the packaging package of the enclosed container according to claim 1 or 2, the case body is a box formed in a substantially rectangular parallelepiped, and the bag body correction The members are arranged to face each other on at least two surfaces of the case body facing each other across the enclosing container among the bottom surface portion, the side surface portion, and the upper surface portion of the case body, and the surface of the case body facing each other It is a plate-like body formed in the same or smaller size. Therefore, the first bag body can be held on the two surfaces, and the first bag body can be supported in a wide range as compared with the case where the first bag body is held by the columnar body or the frame body. is there.

  Here, since the first bag body is formed of a flexible sheet body, it is not always necessary to use one that matches the inner shape of the case body, and a larger one than the inner shape of the case body, It can be stored and used in the case body. If the first bag body is not limited to a specific size, the packaging tool can be easily configured at a low cost, while the portion of the first bag body that does not come into contact with the bag body correction member tends to be loose. If the slack is generated so as to protrude toward the inside of the case body, the amount of expansion of the first bag body in a reduced pressure environment is increased, which is not preferable.

  Therefore, by supporting the first bag body in a wide range using the bag body correction member as a plate-like body, it is possible to reduce the occurrence of slackness of the first bag body that is convex inward, while realizing low cost, There is an effect that the amount of expansion of the first bag body under a reduced pressure environment can be suppressed.

  According to the packaging package of the enclosing container according to claim 5, in addition to the effect of the packaging package of the enclosing container according to claim 1 or 2, both the case body and the bag body correcting member are formed in a substantially rectangular parallelepiped. The box body that forms the bag body correction member is formed so as to be housed in the box body of the case body. Therefore, the shape difference between the outer shape of the first bag body and the inner shape of the case body can be made narrow by correction by the bag body correction member, and the bag body correction member (column body, frame body, plate body body) Compared to a non-identical bag body correction member, which supports the first bag body locally, there is an effect that the first bag body can be most closely approximated to the inner shape of the case body. For this reason, compared with the case where the shape of a bag body correction member and the inner shape of a case body are not the same, the volume change of the 1st bag body before and behind pressure reduction is suppressed further, and the 1st bag in a pressure reduction environment There is an effect that changes in internal pressure of the body can be suppressed.

  According to the packaging package of the enclosed container according to claim 6, in addition to the effect exhibited by the packaging package of the enclosed container according to claim 1 or 2, the case body includes a bottom surface portion and a side surface erected from the bottom surface portion. And a top surface portion that covers an end portion of the side surface portion opposite to the bottom surface portion side, and is a box formed in a substantially rectangular parallelepiped shape. The bag body correction member includes at least a bottom surface portion and four side surface portions continuous to the bottom surface portion, and these five surfaces have sizes similar to the bottom surface portion and the side surface portion of the case body. It is a substantially rectangular parallelepiped box-shaped member whose upper surface is opened when the side surface portion is raised substantially perpendicular to the bottom surface portion. The enclosing container is disposed inside the first bag body while being housed inside the bag pair correcting member in a box shape. Here, the bag body correction member can have its four side surfaces individually rocked with the end on the bottom surface side as the base.

  Therefore, the side surface portion of the bag body correction member can be expanded in the direction closer to the box body of the case body, that is, the gap generated by the difference between the inner shape of the case body and the outer shape of the bag body correction member There is an effect that the shape of the member can be reduced by appropriately correcting according to the inner shape of the case body. According to this, strict dimensional management is not required for the bag body correction member and the case body. This is because the dimensional difference between the two can be absorbed by the degree of freedom of the bag body correction member. Therefore, there is an effect that the bag body correction member and the case body can be easily manufactured.

  According to the packaging package of the enclosing container according to claim 7, in addition to the effect exhibited by the packaging package of the enclosing container according to claim 6, the first bag body is a substantially rectangular parallelepiped whose upper surface is opened when the inside is inflated. Since it is a gusset bag, the first bag body can be formed into a substantially rectangular parallelepiped when the bag body correcting member is accommodated and the inside thereof is inflated. Here, when the outer shape of the first bag body is corrected to a shape that approximates the inner shape of the case body, if the original shape of the first bag body is different from the inner shape of the case body, the first bag after correction is corrected. The outer shape of the body is roughly approximated to the inner shape of the case body, but microscopically (by deformation corresponding to the inner shape of the case body) becomes a shape in which slackness or deflection occurs. Such slack or deflection increases the degree of freedom of the sheet body (first bag body) at that portion and causes the first bag body to expand.

  However, since the first bag body is formed of a gusset bag, the outer shape of the first bag body can be approximated to the inner shape of the case body without correction by the bag body correction member, As a result, the outer shape of the first bag body is not greatly deformed even when the correction by the bag body correction member is performed. Therefore, the outer shape of the first bag body corrected by the bag body correcting member can be prevented from being slackened or bent, and the expansion of the first bag body can be strictly controlled.

  According to the packaging package of the enclosure container according to claim 8, in addition to the effect exerted by the packaging package of the enclosure container according to any one of claims 1 to 7, the bag body correction member has an inner shape of the case body, It is provided with a filler that fills a space generated by the shape difference from the outer shape of the enclosure. Thus, the outer shape of the first bag body can be approximated to the inner shape of the case body by spreading the first bag body from the inside to the shape corresponding to the inner shape of the case body with the filler. As a result, there is an effect that it is possible to suppress the volume change of the first bag body before and after the pressure reduction and to suppress the internal pressure change of the first bag body in the reduced pressure environment. In general, the filler can fill the space by changing the filling form according to the space shape. Therefore, it can be used regardless of the shape of the case body and the enclosure, and it is not necessary to prepare various bag body correction members according to the inner shape of the case body and the outer shape of the enclosure. In other words, regardless of the shape of the case body and the enclosing container, the bag body correction member can be used in the same standard, facilitating the management of the member and reducing the cost. There is an effect that can be.

  According to the packaging package of the enclosure according to claim 9, in addition to the effect exhibited by the packaging package of the enclosure according to any one of claims 1 to 8, the bag body correction member covers the enclosure and the case body Since the flexible film body that reduces the difference in shape between the container and the enclosing container is provided, the shape of the first bag body from the inside to the inner shape of the case body is covered by the enclosing container covered with the film body. The outer shape of the first bag body can be approximated to the inner shape of the case body. As a result, there is an effect that it is possible to suppress the volume change of the first bag body before and after the pressure reduction and to suppress the internal pressure change of the first bag body in the reduced pressure environment.

  According to the packaging package of the enclosure according to claim 10, in addition to the effect of the packaging package of the enclosure according to any one of claims 1 to 9, the bag body correction member is formed of a porous material. . Therefore, even if it is a bag body correction | amendment member of the same shape and the same volume, more gas can be sealed by the 1st bag body compared with the thing formed with the non-porous material. As a result, even if the first bag body is gas permeable, there is an effect that the rate of decrease of the internal pressure of the first bag body under a reduced pressure environment can be made slow.

  According to the packaging package of the enclosure according to claim 11, the enclosure is enclosed and sealed in the first bag formed of a flexible sheet material. The first bag body is housed in a case body, and a second bag body sealed with gas is disposed in an inner space of the case body that is not occupied by the first bag body on the outer peripheral side of the first bag body. Established. When the external pressure outside the second bag body is a reduced pressure environment lower than the internal pressure inside the second bag body, the expansion of the second bag body in the case body direction is suppressed by the rigidity of the case body, Further, the first bag body is pressed by the expansion force of the second bag body, and the expansion of the first bag body in a reduced pressure environment is suppressed. Therefore, even under a reduced pressure environment, the atmospheric pressure, which is the pressure applied to the sealed container in the first bag body, does not change significantly from the environment before the pressure reduction (the original manufacturing environment). In other words, even in a reduced pressure environment, there is an effect that the pressure balance inside and outside the sealed container can be maintained in substantially the same state as in the normal pressure environment in the first bag.

  When the first bag body containing the sealed container expands in a reduced pressure environment, the air pressure in the first bag body decreases in inverse proportion to the expansion amount. That is, the atmospheric pressure, which is a pressure applied to the sealed container from the outside, decreases. Here, since the first bag body that is inflated inside the case body can be regulated by the rigidity of the expansion case body and the expansion force of the second bag body, the air pressure in the first bag body is large even in a reduced pressure environment with a simple configuration. The decline can be avoided.

  If a large pressure drop occurs in the first bag body, the pressure of the gas in the enclosure becomes relatively high, and the internal pressure in the enclosure acts in the direction of pushing out the fluid. In the case where an opening for introducing and introducing a fluid is provided in the sealed container, or when a seal failure occurs, the fluid leaks out of the sealed container due to the pressure of the gas in the sealed container. However, even under a reduced pressure environment, the pressure inside the first bag body can be maintained, and the pressure balance inside and outside the sealed container can be maintained in substantially the same state as under the normal pressure environment, so that no fluid leaks from the sealed container.

  Moreover, since the packing tool should just have the structure for suppressing the expansion | swelling of a 1st bag body, the polyolefin resin which is a versatile resin material, for example, a polyester-type in a 1st bag body, for example Inexpensive general-purpose products such as a resin, a vinyl resin, a polyamide resin, and an acrylic resin can be used. Further, the case body only needs to have a rigidity that restricts the expansion of the first bag body. For example, a thick resin container or a cardboard paper container can be used. Therefore, compared with the case where the enclosure is packed using an expensive metal case, a desiccator, or the like, the packing tool can be configured with an inexpensive material, and the manufacturing cost can be reduced.

  According to the packaging method for an enclosure according to claim 12, the packaging container packaging package according to any one of claims 1 to 11 is used for packaging the enclosure and opened by the enclosure container storing step. An enclosure or an enclosure and a bag correction member are inserted and stored in the first bag. And after the enclosure container storing step, the first bag body is formed in the passage formation sealing step in a state where a communication passage is formed to communicate the enclosure container or the portion in which the enclosure container and the bag body correction member are stored and the outside. Sealed by. Further, before or after the enclosure container storing step, the first bag body is stored in the case body partially opened by the first bag body storing step. And after a 1st bag body accommodation process, the excess part of a 1st bag body is folded by a folding process, pushing out the gas in a 1st bag body from a communicating path. Thereafter, in the sealing and closing step, the communication path is sealed to seal the first bag body, and the open portion of the case body is closed. Therefore, excess gas does not remain in the sealed first bag body as compared with the inner volume of the case body, and the volume of the first bag body does not exceed the inner volume of the case body. Therefore, it is possible to avoid a situation in which the first bag body cannot be stored in the case body, and it is possible to satisfactorily store the first bag body in the case body.

  According to the method for packing an enclosure according to claim 13, in addition to the effect exhibited by the method for packing an enclosure according to claim 12, the first bag body is formed larger than the outer shape of the enclosure container or the bag body correction member. In addition, in the state in which the enclosing container or the enclosing container and the bag body correcting member are accommodated, the opening portion has an excess portion that is not occupied by the enclosing container or the bag body correcting member. The width direction of the first bag body is sealed, leaving a part in the width direction of the first bag body in the vicinity of the enclosing container or the bag body correction member housed in the bag body, and the unsealed portion extends to the opening. The surplus portion of the first bag body is sealed along the direction intersecting the width direction so as to extend to form a communication passage.

  Therefore, the gas can be pushed out (discharged) to the outside of the first bag body through the communication passage, and there is an effect that the appropriate volume of gas can be discharged smoothly. Furthermore, the sealing for sealing the first bag body may be performed on the communication path. In other words, since the communication path can be blocked regardless of the sealing position as long as it is on the communication path, there is an effect that sealing errors can be reduced.

  According to the method for packing an enclosure according to claim 14, the packaging tool for an enclosure container according to any one of claims 1 to 11 is used for packaging the enclosure, Alternatively, the sealed container and the bag body correction member are inserted and stored in the opened first bag body. After the enclosure container storing step, the first bag body is stored in a partially opened case body by the first bag body storing step. Thereafter, the first bag body is sealed and sealed by the sealing and closing step, and the open portion of the case body is closed.

  Therefore, by storing the first bag body in the case body, the excess amount (compared to the space volume of the difference between the case body volume and the volume of the stored item in the first bag) compared to the case body volume. The gas can be discharged from the opening of the first bag body. For this reason, compared with the case where the sealed bag body is stored in the case body after the first bag body is sealed, it is possible to reliably avoid a situation in which the first bag body cannot be stored in the case body. There is an effect that one bag body can be satisfactorily stored in the case body.

  The recording head 1 is mounted on a carriage that is movable in the width direction (main scanning direction) of a recording medium and is mounted on an ink jet recording apparatus. When performing recording, the recording head 1 reciprocates in the width direction (main scanning direction) of the recording medium while ejecting ink. In such a case, the tube connected to the recording head 1 moves in conjunction with the carriage operation, and the ink in the tube swings. When the oscillation (dynamic pressure) of the ink in the tube is transmitted to the ink stored in the recording head 1, the ink ejection performance is affected and the print quality is deteriorated. Therefore, an air layer is provided in the ink reservoir 2 (ink reservoir chambers 2a to 2d), and the ink in the tube and the ink in the ink reservoir 2 are interrupted by the air layer, so that the ink in the tube The generated dynamic pressure is prevented from being transmitted to the ink in the ink reservoir 2.

Each color ink is introduced into the nozzle from the ink reservoir 2. Further, the ink introduced into the nozzle is ejected from the tip (recording medium side) of the nozzle. The tip of the nozzle that discharges ink serves as an ink discharge port, and a mortar-shaped (concave) meniscus is formed from the inner wall of the nozzle toward the center by the ink liquid level filled in the nozzle. .

  An ink supply unit 4 for supplying ink from the ink cartridge to the ink storage unit 2 is provided on the upper left side of the recording head 1 so as to protrude outward (left side of the sheet). The ink supply unit 4 has a total of four ink supply ports 4a to 4d, one for each type corresponding to the type of ink, and each of the ink supply ports 4a to 4d has four ink storage chambers 2a. It communicates with each of ˜2d. The ink supply ports 4a to 4d are connected to tubes sent from the ink cartridges of the respective colors (cyan, magenta, yellow, black), and the inks of the respective colors are supplied from the ink cartridges by the tubes. Are introduced into the corresponding ink reservoirs 2 (ink reservoir chambers 2a to 2d).

  On the upper surface of the ink supply unit 4, a supply port seal 5 that closes the ink supply ports 4 a to 4 d is provided. On the lower surface of the supply port seal 5, convex portions that are fitted into the ink supply ports 4 a to 4 d are provided (not shown). The supply port sealing device 5 fits the convex portions into the ink supply ports 4a to 4d and seals the ink supply ports 4a to 4d.

  The hermetically sealed package 7 encloses the recording head 1 and includes a main body 8 on which the recording head 1 is placed and a lid 9 that covers the main body 8. The main body 8 is a molded product of polyoxymethylene resin having an inner shape corresponding to the outer shape of the recording head 1. The main body 8 has a bottom surface 8c and a wall surface 8d erected from the periphery of the bottom surface 8c. The main body 8 is formed in a substantially rectangular shape when viewed from above, and an upper portion thereof is opened for mounting the recording head 1. .

  The bottom surface 8c has two surfaces having different depths from the top surface, and one surface on the upper side (first bottom surface 8c1) and the other surface on the lower side (second bottom surface 8c2) have a depth (high). S) is formed in a step shape continuously provided at a predetermined interval in the direction. The first bottom surface 8c1 is for holding the ink supply unit 4 of the recording head 1, and is in contact with the lower surface of the ink supply unit 4 of the recording head 1 to be placed. The second bottom surface 8c2 supports the nozzle forming surface 3 side of the recording head 1, and a fixing member 8b for fixing the mounted recording head 1 in the main body 8 faces upward from the second bottom surface 8c2. Standing up. The fixing member 8b is disposed according to the unevenness of the outer periphery of the side surface of the recording head 1 (avoid the position occupied by the recording head 1 mounted), and the inner wall of the wall surface 8c, the fixing member 8b, Thus, the mounted recording head 1 is fixed to a predetermined position so as not to be movable. In the present embodiment, a plurality of fixing members other than the illustrated fixing member 8b are arranged along the inner wall of the side wall 8d (not shown). Further, the side surface of the recording head 1 described above indicates a surface that becomes a side surface when the nozzle forming surface 3 is a lower surface and the opposite side of the lower surface is an upper surface.

  A rubber packing 6 serving as a storage cap for the nozzle forming surface 3 is disposed at a position facing the nozzle forming surface 3 of the recording head 1 while being fixed by the fixing member 8b. The rubber packing 6 is made of synthetic rubber having ink resistance, and is formed in a size that covers the nozzle forming surface 3.

  Further, the rubber packing 6 has a recess 6 a corresponding to a region where the nozzle is formed on the nozzle forming surface 3, and a sealed internal space is formed when the rubber packing 6 is in close contact with the nozzle forming surface 3. It is like that.

  On the outer periphery of the side wall 8d, first engagement portions 8a that engage with the lid body 9 are provided so as to protrude outward at substantially central portions of the side surfaces along the longitudinal direction. One first engaging portion 8a is provided on each of the side surface on the front side of the paper surface and the side surface on the back side of the paper surface facing the side surface. When the lid body 9 is assembled, the main body 8 is inserted inside the lid body 9 and engaged with the lid body 9 by the first engagement portion 8a.

  The lid body 9 is a molded product of polyoxymethylene resin, and has an upper surface 9c and a side wall 9d erected downward from the periphery of the upper surface 9c. The lower part is formed open so that the main body 8 can be inserted.

  In addition, on the outer periphery of the side wall 9d, two second engaging portions 9a that are respectively engaged with the two first engaging portions 8a of the main body 8 are formed at substantially central portions of the side surfaces along the longitudinal direction. ing. The second engaging portion 9a is formed by providing a notch in a part of the side wall 9d, and a flat plate 9a1 along the standing direction of the side wall 9d and a side wall at the tip of the flat plate portion 9a1. An L-shaped portion 9a2 bent toward the inner side of 9d is provided. The lower surface of the L-shaped portion 9a2 is provided with an inclination from the lower protruding end toward the inside of the lid body 9.

  When the main body 8 and the lid body 9 are matched and the main body 8 is inserted into the lid body 9, the first engaging portion 8 a protruding from the main body 8 is located below the second engaging portion 9 a of the lid body 9. , And slides on the inclined portion of the L-shaped portion 9 a 2 to enter the inside of the lid body 9. On the other hand, the second engaging portion 9a of the lid body 9 is pressed by the first engaging portion 8a when the first engaging portion 8a enters in the insertion direction, and is gradually elastically deformed outward. When the first engaging portion 8a passes the tip of the L-shaped portion 9a2, the second engaging portion 9a is elastically restored, and the first engaging portion 8a and the second engaging portion 9a are engaged. The lid body 9 is locked to the main body 8.

  In such a locked state, the lower surface (nozzle formation surface 3) of the recording head 1 encapsulated in the sealed package 7 contacts the bottom surface 8c of the main body 8, and the upper surface of the recording head 1 contacts the upper surface 9c of the lid 9. In this state, a predetermined pressure is applied. For this reason, the rubber packing 6 is in close contact with the nozzle forming surface 3 of the recording head 1, and the tip (ink discharge port) of the nozzle is sealed, so that the ink is sealed in the recording head. At this time, the tip of the nozzle is located in a sealed space formed by the recess 6 a of the rubber packing 6. That is, by encapsulating the recording head 1 with the sealed package 7, the recording head 1 becomes a sealed container in which ink as a fluid is sealed together with air.

  FIG. 2 is a view for explaining the packaging package 10 of the present embodiment in which the sealed package 7 encapsulating the recording head 1 is packed with the packing tool 20. 2A is an exploded perspective view of the present packaging package 10, and FIG. 2B is a cross-sectional view of the packaging package 10 as viewed from the direction A in FIG. 2A.

  As shown in FIGS. 2A and 2B, the packing tool 20 includes an inner box 11 that encloses the sealed package 7, a bag body 12 that seals the inner box 11, and a case that houses the bag body 12. And a body 13. In addition, although illustration is abbreviate | omitted, the hermetic package 7 is enclosed in the inner box 11 in the state where the convex part which enclosed air was encapsulated in the polyethylene foam cushioning material sheet formed in the whole surface. .

  The case body 13 is a cardboard box formed in a substantially rectangular parallelepiped shape, and accommodates the inner box 11 sealed in the bag body 12 therein. The case body 13 has a bottom surface formed in a substantially rectangular shape, four side surfaces erected from the periphery of the bottom surface, and an upper surface that closes an opening formed at an end portion on the upper side (anti-bottom side) of the four side surfaces. And. The upper surface is formed by four lid members connected to the four side surfaces. Each of the lid members is configured to be rotatable about a boundary with each side surface connected to each other. When the lid member is rotated inward, the upper opening of the case body 13 is closed to form an upper surface. When the case body 13 is rotated, the upper opening of the case body 13 is opened.

  The material constituting the case body 13 is not limited to corrugated cardboard, but can suppress the expansion of the bag body 12 under a reduced pressure environment, has a higher rigidity than the bag body 12, and is inexpensive. Can be appropriately selected. Examples of such materials include thin plates such as paperboard and plywood, glass fiber reinforced epoxy resin substrates, and polyolefin resins, polyester resins, vinyl resins, polyamide resins, and acrylic resins, which are general-purpose resin materials. And those in which such a resin is filled with a filler.

  The bag 12 is formed of a resin-made flexible film that can be heat-sealed, and serves to seal the inner box 11 that encloses the sealed package 7. This bag body 12 is formed of two rectangular film bodies, and before insertion of the inner box 11, three sides are sealed and one is opened to form an opening 12a (see FIG. 3). It has become a mode. The opening 12a is heat-sealed by heat sealing after the inner box 11 is inserted from the opening 12a.

  The bag body 12 is corrected to a shape approximate to the inner shape of the case body 13 by the inner box 11 and stored in the case body 13. For this reason, the bag body 12 has a surface area equal to or greater than the inner surface area of the case body 13 in order to be arranged (contacted) along the inner shape of the case body 13. Moreover, the volume of the bag body 12 is larger than the volume of the inner box 11, has a space in the bag body 12 that is not occupied by the inserted inner box 11, and is a film body above the inserted inner box ( The inner box 11 is stored in a state where the opening side is left.

  The resin material constituting the bag body 12 is a general-purpose resin material such as polyolefin resin, polyester resin, vinyl resin, vinylidene resin, polyamide resin, acrylic resin, and a metal vapor deposition layer on such resin. Or a laminate film sandwiched between metal laminate layers or the like is used as appropriate. In the present embodiment, the bag body 12 is made of a polyethylene resin having a good moisture barrier property for the inner layer and the outer layer, and an ethylene vinyl alcohol copolymer having an intermediate layer sandwiched between the inner layer and the outer layer having a low gas permeability. Alternatively, a three-layer structure made of nylon resin having a thickness of 80 μm is used.

  As the gas permeability of the bag body 12 increases, the air inside the bag body 12 is released to the outside of the bag body 12 under a reduced pressure environment, and the rate of decrease in the atmospheric pressure inside the bag body 12 increases. For this reason, the bag body 12 includes an intermediate layer having a low gas permeability.

  The inner box 11 is a paper box that is formed in a rectangular parallelepiped shape and encloses the sealed package 7. The inner box 11 is a correction member that is disposed inside the bag body 12 and corrects the shape of the bag body 12 to approximate the inner shape (form and size) of the case body 13. The inner box 11 is formed so that its outer shape is similar to the inner shape of the case body 13 (preferably a similar relationship). In the present embodiment, the inner box 11 has each surface facing each inner surface of the case body 13 and has an outer shape similar to the inner shape of the case body 13. In particular, in view of ease of manufacture, a substantially rectangular parallelepiped box is used for the inner box 11 and the case body 13. When the inner box 11 is contained in the bag body 12, the bag body 12 is regulated by the outer surface of the inner box 11 and cannot enter inward of the inner box 11. Therefore, it is possible to perform correction to approximate the shape of the bag body 12 to a substantially rectangular shape corresponding to the outer shape of the inner box 11, that is, the inner shape of the case body 13.

  The outer dimensions of the inner box 11 are the length in the longitudinal direction (X1), the length in the direction intersecting the longitudinal direction (width, Y1), and the height (Z1), respectively. Is designed to be smaller than each of the length (X2), the width (Y2), and the height (Z2), and a gap for inserting the bag body 12 between the opposing surfaces of the inner box 11 and the case body 13 Designed to ensure the size.

  Specifically, the outer dimension (X1) of the inner box 11 is obtained by subtracting the thickness (t) of the bag body 12 (stored in the case body 13) from the inner dimension (X2) in the longitudinal direction of the case body 13. The length (X2-2t) is the maximum, and is not more than the maximum length. In the present embodiment, the outer dimension (X1) of the inner box 11 is formed to be approximately 0.1 to 3 mm smaller than the inner dimension (X2) in the longitudinal direction of the case body 13. For this reason, the two side surfaces intersecting with the longitudinal direction of the inner box 11 are arranged at a distance of approximately 0.1 to 3 mm (with a slight gap) from the inner surface facing the case body 13.

  The outer dimension (Y1) of the inner box 11 is a length obtained by subtracting the thickness (t) of the bag body 12 (stored in the case body 13) from the inner dimension (Y2) in the width direction of the case body 13. (Y2-2t) is set to the maximum, and the maximum length is not more than this. In the present embodiment, the outer dimension (Y1) of the inner box 11 is formed to be approximately 0.1 to 3 mm smaller than the inner dimension (Y2) in the longitudinal direction of the case body 13. For this reason, the two side surfaces along the longitudinal direction of the inner box 11 are arranged approximately 0.1 to 3 mm away from the inner surface facing the case body 13 (with a slight gap). Thereby, on the inner surface of the side surface of the case body 13, most of the facing bag bodies 12 abut on the inner surface of the case body 13.

  Further, the outer height (Z1) of the inner box 11 is determined by the thickness (t) of the bag body 12 that wraps around the bottom surface of the case body 13 from the height (Z2) inside the case body 13 and the upper surface of the inner box 11. The height obtained by subtracting the folding thickness when the bag body 12 is folded is set to the maximum, and is set to be equal to or less than the maximum height. In the present embodiment, the outer height (Z1) of the inner box 11 is formed to be approximately 0.1 to 3 mm smaller than the inner height (Z2) of the case body 13. The bottom surface of the inner box 11 is placed on the inner surface (bottom surface) facing the case body 13 with the bag body 12 in between. The upper surface of the inner box 11 is disposed at a distance of approximately 0.1 to 3 mm from the opposing inner side surface (upper surface) of the case body 13, and between the opposing surfaces of the upper surface of the inner box 11 and the upper surface of the case body 13. The folded bag body 12 is filled.

  Thus, by holding the bag body 12 in the inner box 11 having a shape that approximates the inner shape of the case body 13, most of the bag body 12 abuts (adheres) to the inner surface of the case body 13 or It can be disposed at a close position, and its shape can be approximated to the inner shape of the case body 13. The smaller the volume of the bag body 12 is, the smaller the pressure drop inside the bag body 12 is. Therefore, in the present embodiment, in order to reduce the shape change of the bag body 12 in a reduced pressure environment, the case body 13 In order to eliminate the shape difference between the inner shape of the bag body 12 and the bag body 12, the shape of the bag body 12 is corrected and approximated to the inner shape of the case body 13.

  Here, in order to approximate the outer shape of the bag body 12 to the inner shape of the case body 13 in the inner box 11, the size of the bag body 12 needs to be a size (shape) that matches the inner shape of the case body 13. Absent. Therefore, the general-purpose bag body 12 manufactured in an existing size can be used as it is without preparing the dedicated bag body 12.

  In the present embodiment, the gap formed by the outer surface of the inner box 11 (bag body 12) and the inner surface of the case body 13, that is, the distance between the opposing surfaces of the inner box 11 and the case body 13 is as follows. Even if the internal pressure is reduced due to the expansion of the bag body 12, the pressure after the reduction is designed not to reach the pressure at which the ink leaks.

  Using the packing tool 20, that is, the inner box 11, the bag body 12, and the case body 13, the sealed package 7 (the sealed package 7 in which the recording head 1 is sealed) is packed in the above-described order, whereby the packaging package of the present embodiment. 10 is formed. The packing package 10 in which the recording head 1 is packed by the packing tool 20 is shipped from the factory and supplied to the market. When the distribution channel is air transportation, the recording head 1 is transported in a reduced pressure environment where the atmospheric pressure is lower than that at the time of manufacture. Here, the effect | action in the pressure-reduced environment of the packaging package 10 of this structure is demonstrated with reference to FIG.

  FIG. 4 is a diagram schematically illustrating the operation of the packaging package 10 under a reduced pressure environment. FIGS. 4A and 4B show the normal pressure environment and the reduced pressure environment of the packaging package 10. Each of these states is shown, and FIG. 4 (a ′) and FIG. 4 (b ′) show comparative examples. For ease of illustration, only the rubber packing 6 is shown in the sealed package 7, and other portions are omitted. In the present embodiment, the normal pressure environment is set to about 1 atm, and the reduced pressure environment is set to about 0.7 atm, which is an average pressure in the sky during air transportation.

  FIG. 4A shows the state of the packaging package 10 under a normal pressure environment. The recording head 1 is stored in the inner box 11 in a state where ink is sealed, and is further stored in the bag body 12. It is sealed and encapsulated in the case body 13. Under a normal pressure environment, the inside and outside of the packaging package (inside and outside of the bag body 12) has an atmospheric pressure of approximately 1 atm.

  A rubber packing 6 is in close contact with the nozzle forming surface 3 of the recording head 1 with a predetermined pressing force. The predetermined pressing force is determined by the mechanism for locking the lid 9 to the main body 8 described above, and the backward movement of the nozzle forming surface 3 from the initial state (design value) is within the allowable range of the ink ejection performance. It is set to a pressure that can be accommodated.

  On the other hand, air is sealed above the ink level in the ink reservoir 2 under a normal pressure environment. The pressure P1 at which the air layer presses the ink liquid level in the ink reservoir 2 is approximately 1 atm under a normal pressure environment. Further, the pressure P2 of air sealed in the internal space of the rubber packing 6 (the space formed by the recess 6a of the rubber packing 6 and sealed by bringing the rubber packing 6 into close contact with the nozzle forming surface 3) is also normal pressure. Under the environment, the pressure is approximately 1 atm. Accordingly, since the pressure P1 and the pressure P2 are balanced, a meniscus is formed at the ink discharge port, and the ink in the ink reservoir 2 leaks into the space in the rubber packing 6 or from the inside of the rubber packing 6. It will not leak out.

  FIG. 4 (a ′) shows the state of the comparative packaging package 10 ′ under a normal pressure environment. The recording head 1 is placed in a storage container 11 ′ having a large dimensional difference from the case body 13 in a state where ink is sealed, and is sealed in the bag body 12 together with the storage container 11 ′ and is encapsulated in the case body 13. Has been. Thus, in the comparative example, the inner box 11 which is a correction member that approximates the shape of the bag body 12 to the inner shape of the case body 13 is not provided, and the packing tool includes the storage container 11 ′, the bag body 12, and the like. The case body 13 is constituted.

  Also in the packaging package 10 ′ of the comparative example, the rubber packing 6 is in close contact with the nozzle forming surface 3 with a predetermined pressing force. In the normal pressure environment, the air pressure P1 sealed in the ink reservoir 2 and the air pressure P2 sealed in the internal space of the rubber packing 6 are balanced as in the present embodiment. Will not leak.

  FIG. 4B shows a state of the packaging package 10 under a reduced pressure environment. As in FIG. 4A, the recording head 1 is stored in the inner box 11 in a state where ink is sealed. Further, the bag body 12 is sealed and encapsulated in the case body 13. When the package 10 is placed in a reduced pressure environment, the bag body 12 expands due to a pressure difference between the inside and outside of the bag body 12 because the inside of the bag body 12 is in a normal pressure state. When the bag body 12 expands, the atmospheric pressure (internal pressure) in the bag body 12 decreases in inverse proportion to the amount of expansion.

  Here, in the packaging package 10 of the present embodiment, the bag body 12 includes the inner box 11, and each outer surface of the inner box 11 is positioned at a slight distance from the inner surface of the case body 13. (The shape (form and size) of the bag body 12 is approximated to the inner shape of the case body 13). Therefore, the bag body 12 is inflated only slightly, immediately comes into contact with the case body 13 and its expansion is restricted, and the expansion change of the bag body 12 is suppressed to be small even under a reduced pressure environment.

  In the present embodiment, a large gap is formed on the upper surface of the inner box 11 as compared to the side surface (the distance between the opposing surfaces of the inner box 11 and the case body 13 is large). Since the bag body 12 is folded on the upper surface to fill the gap space, the bag body 12 is inflated only slightly and comes into contact with the case body 13 through the folded portion of the bag body 12 to expand the bag body 12. Is regulated.

  For this reason, the pressure drop in the bag body 12 becomes minute, and the pressure difference with the pressure P2 in the internal space of the rubber packing 6 becomes small, so that the air in the internal space of the rubber packing 6 There is no leakage to the outside. Therefore, the pressure balance at the ink discharge port (nozzle formation surface 3) formed under the normal pressure environment, that is, the pressure balance between the pressure P1 and the pressure P2 is maintained even under the reduced pressure environment and sealed with the rubber packing 6. Ink does not leak from the stopped ink discharge port.

  FIG. 4B 'shows the state of the comparative packaging package 10' under a reduced pressure environment. In the packaging package 10 ′ of the comparative example, the amount of expansion change of the bag body 12 is larger than that of the packaging package 10 of the present embodiment. Therefore, the air pressure in the bag body 12 is greatly reduced. As a result, the pressure difference with the pressure P2 in the internal space of the rubber packing 6 becomes large, the contact portion with the nozzle surface of the rubber packing 6 is deformed to the outside, and the air in the internal space of the rubber packing 6 leaks to the outside. . As a result, the pressure P2 in the internal space of the rubber packing 6 is lower than the pressure P1 of the air sealed in the ink storage portion 2, and the ink in the ink storage portion 2 leaks into the internal space of the rubber packing 6. When the pressure difference between the inside and outside of the rubber packing 6 is considerably large, the ink leaked into the internal space of the rubber packing 6 flows out of the rubber packing 6.

  Further, in the reduced pressure environment, the air in the bag body 12 is released in small amounts due to gas permeability. Here, in the present embodiment, the inner box 11 that is a box is used as a correction member that corrects the shape of the bag body 12. Since the inner box 11 is hollow, the bag body 12 can hold a large amount of air. Thereby, since the amount of air released compared with the amount of air remaining in the bag body 12 can be made small, the rate of decrease in the atmospheric pressure in the bag body 12 can be made slow. In addition, in order to suppress the pressure | voltage fall in the bag body 12 by gas permeation | transmission, you may form the bag body 12 with the laminated film etc. which sandwiched the above-mentioned metal vapor deposition layer or a metal laminate layer.

  Next, with reference to FIG. 3, a packing method for packing the sealed package 7 with the packing tool 20 described above will be described. FIG. 3 is a diagram showing one embodiment of a packing method using the packing tool 20 according to the present embodiment.

  First, the sealed package 7 encapsulating the recording head 1 is housed in the inner box 11 and enclosed in the inner box 11. Next, the inner box 11 is inserted into the bag body 12 through the opening 12a (enclosed container storage step). Thereafter, with the opening 12 a being opened, the bag body 12 is inserted from the opened upper surface of the case body 13 toward the bottom surface of the case body 13, and the inner box 11 is brought into contact with the bottom surface of the case body 13 through the bag body 12. Contact (first bag storage step). In addition, outside the bottom surface of the case body 13, the polyester resin (polyethylene terephthal resin) is used as a base material along the longitudinal direction of the case body 13 and spanned on the side surfaces adjacent to both ends of the bottom surface in the longitudinal direction. Adhesive tape T is stuck and the rigidity of case body 13 is reinforced.

  When the bag body 12 is inserted into the case body 13, the bag body 12 is rubbed by the case body 13 and the inner box 11, and the air between the bag body 12 and the inner box 11 is pushed out and discharged from the opening 12a. Is done. When the insertion of the bag body 12 is completed, the bag body 12 is heat-sealed, the film body on the front and back surfaces is heat-sealed, and most of the opening 12a is sealed and formed by a part of the opening 12a. A narrow air discharge passage 12b having an air discharge port 12a1 is formed (passage formation sealing step).

  The air discharge port 12a1 is manufactured by forming an L-shaped seal portion 12c on the bag body 12 by heat sealing. Specifically, first, the bag body 12 is heat-sealed linearly (with a predetermined seal width) in the width direction (the direction along the longitudinal direction of the inner box 11) to form the first direction seal portion 12c1. The formation position of the first direction seal portion 12 c 1 is above the inner box 11 and in the vicinity of the upper surface of the inner box 11. Further, the seal length of the first direction seal portion 12c1 is shorter than the width direction of the bag body 12, and the tip of the first direction seal portion 12c1 is a predetermined length before the end portion of the bag body 12 in the width direction. . That is, a portion where heat sealing has not been performed remains at one end of the bag body 12 in the width direction, and the opened state of the bag body 12 is maintained. Then, the second direction seal portion 12c2 is formed by linearly heat-sealing from the front end of the first direction seal portion 12c1 to the opening 12a in a direction intersecting the width direction of the bag body 12. Thus, the bag body 12 is sealed in an L shape, and an air discharge port 12a1 extending from the tip of the first direction seal portion 12c1 to the opening 12a is formed. For this reason, most of the opening 12a of the bag body 12 is sealed, while the inside and outside of the bag body 12 communicate with each other through the air outlet 12a1 (see FIG. 3A).

  Next, while extruding the air in the bag body 12 from the air discharge port 12a1, the excess portion of the bag body 12 above the inner box 11 is folded so that the opening of the air discharge port 12a1 is exposed on the surface (folding). Step, see FIG. 3 (b)). Subsequently, the air discharge port 12a1 is heat-sealed from one end to the other end in the vicinity of the opening to form the final seal portion 12d. Thereby, the air discharge port 12a1 is shut off and the bag body 12 is sealed. After the bag body 12 is sealed, the four lid members of the case body 13 in an open state are folded inward to close the upper surface of the case body 13 (see a sealing / blocking step, see FIG. 3C). Thereafter, the adhesive tape T is stretched over and attached from one side surface adjacent to the longitudinal end of the upper surface of the case body 13 to the side surface facing the one side surface, and the upper surface of the case body 13 is prohibited from being opened. . Further, the adhesive tape T is wound around and pasted in a direction intersecting the longitudinal direction of the upper surface of the case body 13, and the case body 13 is sealed. The sealed package 7 that encloses the recording head 1 is packaged by sequentially performing such steps, and the package 10 that packages the sealed package 7 (recording head 1) is completed.

  The outer shape of the inner box 11 approximates the inner shape of the case body 13, and the distance between the opposing surfaces is a slight distance. On the other hand, the bag body 12 sufficiently accommodates the inner box 11 and has a larger volume than the volume of the inner box 11 and the inner volume of the case body 13. Therefore, if the bag body 12 is sealed before being stored in the case body 13, the air present in the bag body 12 cannot be absorbed in the gap between the inner box 11 and the case body 13, and the bag The body 12 may not be housed in the case body 13. However, as shown in this embodiment, since the bag body 12 is sealed after being accommodated in the case body 13, the bag body 12 does not become impossible to be accommodated in the case body 13. Further, since the final heat sealing is performed after the bag body 12 is folded while air is discharged from the air discharge port 12a1, the storage space for the excess portion of the bag body 12 is secured in the case body 13 before the bag body. 12 can be sealed. Therefore, it is possible to avoid a situation in which the bag body 12 cannot be stored because the storage space for the excess portion of the bag body 12 cannot be secured.

  It should be noted that the enclosure container storing step for inserting the bag body 12 into the case body 13 may be a step before the inner box 11 is stored in the bag body 12 or a step after the passage formation sealing step. .

  Further, as shown in FIG. 5, after the passage formation sealing step, the portion surrounded by the first direction seal portion 12c1 and the second direction seal portion 12c2 of the bag body 12 is removed, and then folded. You may make it perform a process. In this case, the sealing and closing step is performed by folding three lid members including two long lid members among the four lid members of the case body 13 with the air discharge passage 12b exposed to the outside of the case body 13. The upper surface of the case body 13 is closed (see FIG. 5C), and then the air discharge passage 12b is placed on the upper surface of the case body 13 and then the remaining one lid member is folded. According to this, since it is not necessary to accommodate the excess part (the part to be removed surrounded by the first direction seal portion 12c1 and the second direction seal portion 12c2) of the bag body 12 in the case body 13, the bag body The situation where the storage of 12 becomes impossible can be avoided more reliably.

  Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 6 is a diagram schematically showing the internal structure of the packaging package 100 of the second embodiment in front view. In addition, the same code | symbol is attached | subjected to the same part as above-mentioned 1st Embodiment, and the description is abbreviate | omitted.

  The packaging package 100 of the second embodiment includes a bag body 12 and a case body 13 as a packaging tool 20 for packaging the recording head 1 encapsulated in the sealed package 7 as in the first embodiment. Instead of the inner box 11, two plate-like members 14 are provided as correction members for correcting the shape of the bag body 12.

  The plate-like member 14 is disposed so as to oppose the upper surface and the bottom surface of the case body 13, and is formed in a shape that approximates the inner surface of the opposing case body 13. Specifically, the plate-like member 14 has a rectangular shape, and the longitudinal direction thereof is the same length as the outer dimension (X1) of the inner box 11, and the inner dimension (X2) of the case body 13 in the longitudinal direction. The length (X2-2t) obtained by subtracting the thickness (t) of the bag body 12 (contained in the case body 13) from the maximum is set to be equal to or less than the maximum length. Further, the width of the plate-like member 14 is the same length as the outer dimension (Y1) of the inner box 11, and the inner dimension (Y2) in the width direction of the case body 13 (stored in the case body 13). The length (Y2-2t) obtained by subtracting the thickness (t) of the bag body 12 is set to the maximum, and is not more than the maximum length (see FIG. 2 for the dimensions of the inner box 11 and the case body 13).

  One plate-like member 14 is disposed so as to contact the inside of the bottom surface of the case body 13 with the bag 12 interposed therebetween, and the sealed package 7 is placed on the plate-like member 14, and further above the sealed package 7. In the state where the other plate-like member 14 is arranged, each plate-like member 14 and the sealed package 7 are included in the bag body 12. The upper plate-like member 14 has a gap that accommodates the excess bag 12 between the plate-like member 14 and the opposite inner surface (upper surface) of the case body 13, downward from the inner side of the upper surface of the case body 13. Be placed.

  Since the plate-like member 14 has a simple shape that is easy to manufacture, the correction member can be easily manufactured and the manufacturing cost can be reduced. The plate-like member 14 is not limited to those disposed on the upper surface side and the bottom surface side of the case body 13, and may be disposed on each of the two opposing side surfaces. Further, the plate-like member 14 may be arranged not only on two opposing surfaces but also on four surfaces surrounding the sealed package 7.

  In order to approximate the bag body 12 to the rectangular parallelepiped shape that is the inner shape of the case body 13, it is only necessary to support the eight vertices forming the rectangular parallelepiped. Accordingly, the correction member is disposed in the vicinity of the edge of at least two surfaces facing each other across the sealed package 7 among the bottom surface, the side surface, and the top surface of the case body 13, and extends along at least one pair of opposite sides of each surface. It is only necessary to provide extended portions that are respectively extended. As a correction member provided with such an extended portion, not only the plate-like member 14 but also a frame body which is formed in a rectangular shape whose outer peripheral shape is the same as that of the plate-like member 14 and which is hollow inside the peripheral portion is a correction member Is exemplified. Moreover, four columnar bodies arrange | positioned along four corners are illustrated.

  The packaging is no longer needed after unpacking and will be discarded or reused. In such a case, if the correction member is composed of four columnar bodies, at least two frame bodies, or the plate-like member 14, the handling is easy, and therefore the effort of the unpacker who performs the disposal or reuse process is reduced. Can be reduced. The columnar body, the frame body, and the plate-like member 14 are configured by appropriately using various materials such as resin, metal, ceramics, and paper, and the correction member is formed of a porous body (porous material). May be.

  Next, a third embodiment of the present invention will be described with reference to FIG. FIG. 7 is a diagram schematically illustrating the internal structure of the packaging package 110 according to the third embodiment in a front view. In addition, the same code | symbol is attached | subjected to the same part as above-mentioned 1st Embodiment, and the description is abbreviate | omitted.

  The packaging package 110 of the third embodiment includes a bag body 12 and a case body 13 as a packaging tool 20 for packaging the recording head 1 encapsulated in the sealed package 7 as in the first embodiment. Instead of the inner box 11, a rigid urethane foam granular material 15 is provided as a correction member for correcting the shape of the bag 12. Since the rigid urethane foam is a porous body (porous material), it contains a lot of air. Therefore, even if the bag body 12 is filled in a large amount, a large amount of gas can be sealed in the bag body 12. As a result, even if the bag body 12 has gas permeability, the rate of decrease in atmospheric pressure in the bag body 12 under a reduced pressure environment can be slowed down.

  Each of the rigid urethane foam granules 15 is a lump formed in an indefinite shape, and is shaped to fit into a gap generated by a shape difference between the case body 13 and the sealed package 7. Since this rigid urethane foam granular material 15 is amorphous as a whole, it flows in the bag body 12 and fills the gap generated by the shape difference between the sealed package 7 and the case body 13. As a result, the bag body 12 is expanded outward, and the shape thereof is corrected along the inner shape of the case body 13. For this reason, even if the outer shape of the sealed package 7 is a complicated shape and the shape difference from the inner shape of the case body 13 is large, the shape of the bag body 12 can be corrected according to the shape. .

  In addition, the filler is not limited to the granular material 15 of the hard urethane foam, but may be a granular material of various resins such as flexible urethane foam and styrene foam, and chips of various materials such as paper, pulp, and wood. good.

  Next, a fourth embodiment of the present invention will be described with reference to FIG. FIG. 8 is a diagram schematically showing the internal structure of the packaging package 120 of the fourth embodiment in front view. In addition, the same code | symbol is attached | subjected to the same part as above-mentioned 1st Embodiment, and the description is abbreviate | omitted.

  The packaging package 120 of the fourth embodiment includes a bag body 12 and a case body 13 as a packaging tool 20 for packaging the recording head 1 encapsulated in the sealed package 7 as in the first embodiment. Instead of the inner box 11, as a correction member for correcting the shape of the bag body 12, a flexible sheet packaging body 16 having a convex air packing portion 16 a enclosing air is formed on one surface.

  The sealed package 7 is packaged in a sheet package 16 and sealed in the bag 12. Since the sheet package 16 has flexibility (flexibility), it can be folded to change its shape. Then, by partially changing the number of folds and wrapping the sealed package 7 with a part thicker or thinner, the shape difference between the outer shape of the sealed package 7 and the inner shape of the case body 13 is corrected, that is, The shape of the bag body 12 disposed outside the sheet packaging body 16 can be corrected to approximate the inner shape of the case body 13.

  Even if the sheet packaging body 16 is the same sheet packaging body 16, if the packaging form is changed, the shape of the bag body 12 can be corrected according to the shape of the various case bodies 13, and free as a correction member. The degree is great. Therefore, the sheet packaging body 16 having the same standard can be used for various case bodies without changing the design (the application range is wide). Furthermore, the sheet packaging body 16 is large and easy to handle compared to the rigid urethane foam granules 15 described in the third embodiment. Although the packaging tool 20 needs to be discarded or reused after unpacking, the sheet packaging body 16 has better handling and better workability for unpacking than the granular material that spills or rises. .

  Next, a fifth embodiment of the present invention will be described with reference to FIG. 9 and FIG. FIG. 9 is a perspective view illustrating a configuration of the packaging package 130 according to the fifth embodiment. In the first embodiment, the outer surface of the bag body 12 corrected by the inner box 11 is configured such that the inner surface of the case body 13 contacts or a slight gap is formed. Instead, in the fifth embodiment, a bag body in which air is sealed is disposed between the case body 13 and the bag body 12. In addition, the same code | symbol is attached | subjected to the same part as above-mentioned 1st Embodiment, and the description is abbreviate | omitted.

  The packing package 130 of the fifth embodiment includes an inner box 11, a bag body 12, and a case body 13 as a packing tool 20 for packing the recording head 1 encapsulated in the sealed package 7 as in the first embodiment. I have. In the packing package 130, the sealed package 7 in which the recording head 1 is encapsulated is stored in an inner box 11, and the inner box 11 is further stored in a case body 13 in a state of being sealed by a bag body 12. FIG. 9 shows the packaging package 130 with the bag body 12 taken out from the case body 13.

  The bag body 12 is formed with a seal portion 12e (first heat seal portion 12e1 and second heat seal portion 12e2) by heat sealing, and the film bodies on the two sides of the front and back surfaces are heat-melted (for a predetermined seal width). The bag body 12 is sealed.

  The first heat seal portion 12e1 is formed linearly from one end portion to the other end portion in the width direction of the bag body 12 above the inner box 11 and in the vicinity of the upper surface of the inner box 11. The second heat seal portion 12e2 is formed from one end portion to the other end portion in the width direction of the bag body 12 above the inner box 11 and in the vicinity of the opening 12a of the bag body 12.

  By the first heat seal portion 12e1 and the second heat seal portion 12e2, the inside of the bag body 12 is partitioned into two chambers 12g and 12f in the vertical direction. The lower storage chamber 12g is a sealed space sealed by the first heat seal portion 12e1 and stores the inner box 11. The upper air chamber 12f is a sealed space defined by the first heat seal portion 12e1 and the second heat seal portion 12e2, and is sealed by enclosing air (second bag body 12f). In other words, the air chamber 12f (second bag body) is formed integrally with a part of the bag body 12 by utilizing the remaining part of the inner box 11 accommodated. In the fifth embodiment, the air chamber 12 f (second bag body) is disposed between opposing surfaces of the upper surface of the inner box 11 and the inner surface of the upper surface of the case body 13.

  FIG. 10 is a cross-sectional view illustrating an internal structure of the packaging package 130 according to the fifth embodiment when viewed from the direction B in FIG. FIG. 10A shows a state of the packaging package 130 under a normal pressure environment (approximately 1 atm).

  As shown in FIG. 10A, a bag body 12 in which the inner box 11 is sealed is stored in the case body 13 of the packaging package 130. As in the first embodiment, a sealed package 7 that encloses the recording head 1 is included in the inner box 11. Then, the storage chamber 12g of the bag body 12 is corrected to the shape along the inner surface of the bottom surface and side surface of the case body 13 by the bottom surface and side surface of the inner box 11, and the inner surface of the bottom surface and side surface of the case body 13 is corrected. Most of the facing bag body 12 is in contact with the inner surface of the case body 13. The upper surface of the inner box 11 is disposed (downward) at a predetermined distance from the inner surface of the upper surface of the case body 13. Due to the upper surface of the inner box 11, the upper side of the storage chamber 12 g is corrected to a shape along the inner surface of the upper surface of the case body 13, and at a predetermined distance from the inner surface of the upper surface of the case body 13 (downward). ) Arranged.

  Further, the bag body 12 is bent at the first seal portion 12 e 1, and the air chamber 12 f is overlaid on the storage chamber 12 g on the upper surface of the inner box 11. A gap is formed between the upper surface of the air chamber 12f and the inner surface of the case body 13 facing each other.

  FIG. 10B shows a state of the packaging package 130 shown in FIG. 10A under a reduced pressure environment (approximately 0.7 atm). Under the reduced pressure environment, the pressure inside the bag body 12 is relatively higher than the pressure outside the bag body 12, so that the bag body 12 expands. Here, when the air chamber 12f is expanded, the upper side of the air chamber 12f contacts the inner side of the upper surface of the case body 13, while the lower side contacts the storage chamber 12g. Therefore, the expansion of the storage chamber 12g can be regulated by the case body 13 via the air chamber 12f (second bag body) even if the storage chamber 12g does not contact the inner surface of the case body 13. .

  If the bag body 12 is brought into close contact with the inner surface of the case body, that is, if the entire outer surface of the bag body 12 is held at a position where it abuts against the inner surface of the case body 13, the outer shape of the bag body 12 is the most of the case body 13. The inner shape can be approximated, and the expansion of the bag body 12 can be most suppressed. However, in order to hold the entire outer surface of the bag body 12 at a position where it abuts against the inner surface of the case body 13, it is necessary to process (manufacture) the inner box 11 with strict dimensional accuracy based on the inner dimension of the case body 13. Occurs.

  However, according to the fifth embodiment, since the expansion of the storage chamber 12g is regulated via the air chamber 12f (second bag body) that fills the gap between the inner surface of the case body 13 and the bag body 12, Strict dimensional accuracy is not required for the inner box 11 and the case body 13, and the manufacture of such a packing tool can be facilitated.

  The arrangement position of the second bag 12f is not limited to the upper surface of the inner box 11, and may be a side surface or a lower surface. In the fifth embodiment, the air chamber 12 f (second bag body) is integrally formed as a part of the bag body 12. Instead, the air chamber 12f (second bag body) is formed separately from the bag body 12, and the second bag body is inserted between the facing surfaces of the bag body 12 and the case body 13. You may comprise as follows.

  Further, in the fifth embodiment, the inner box 11 (correction member) is not necessarily required, and a bag body 12 (storage chamber 12g) for sealing the sealed package 7, a second bag body 12f enclosing air, A packing tool may be constituted by the case body 13. According to this, the packaging tool which can reduce a number of parts, can maintain the atmospheric | air pressure in the bag body 12 also in a decompression environment at low cost can be formed.

  Next, a sixth embodiment of the present invention will be described with reference to FIG. FIG. 11 is an exploded perspective view showing the configuration of the packaging package 140 of the sixth embodiment. The packaging tool 20 of the packaging package 100 according to the first embodiment is formed by sealing two rectangular film bodies in three directions as a bag body that seals the sealed package 7 (the inner box 11 included). A bag 12 was used. Further, as a correction member for correcting the shape of the bag body 12, a hexahedral inner box 11 having an upper surface, a side surface, and a bottom surface was used. Instead, in the sixth embodiment, a so-called gusset bag 18 that is a substantially rectangular parallelepiped when the inside is inflated is used as a bag for sealing the sealed package 7, and the correction member corrects the shape of the bag. The packing tool 20 is formed by using the development body 17 having the bottom surface and the five side surfaces. In addition, the same code | symbol is attached | subjected to the same part as above-mentioned 1st Embodiment, and the description is abbreviate | omitted.

  The packaging package 140 of the sixth embodiment includes the case body 13 similar to that of the first embodiment as the packaging tool 20, the development body 17 and the gusset bag 18, and the sheet packaging body 16. It has. The sheet package 16 is the same as the sheet package 16 shown in the fourth embodiment. In the sixth embodiment, the sheet package 16 may be omitted. In the sixth embodiment, the sealed package 7 is accommodated in the development body 17 in a state of being packaged in the sheet packaging body 16.

  As described above, the deployment body 17 is a correction member that houses the sealed package 7 therein and corrects the shape of the bag body that seals the sealed package 7. Specifically, it is a paper member similar to the inner box 11, and includes a substantially rectangular bottom surface and four substantially rectangular side surfaces 17a and 17c connected to each side of the bottom surface. Each of the side surfaces 17a and 17c can stand up with respect to the bottom surface with a connection (shared) side to the bottom surface as a base point. And it is comprised so that the substantially rectangular parallelepiped of the box-shaped aspect by which the upper surface was opened can be formed by standing up each side surface 17a, 17c with respect to the bottom face.

  A margin 17b having a predetermined width is continuously provided along the edge of each of the front-side end and the back-side end of the side surface 17a on the left and right sides in front view. The binding margins 17b are provided to extend outward from both ends of the side surface 17a and are folded toward the inside of the development body 17. When the side surfaces 17a and 17c are erected perpendicularly to the bottom surface, the margin 17b overlaps the back surface of the side surface 17c. About the dimension structure of each surface (side surface 17a, 17c and bottom face) of the expansion body 17, it is the same as that of the corresponding surface (side face and bottom surface) of the inner case 11 (refer FIG. 2) of 1st Embodiment.

  As shown in FIG. 11, the side surfaces 17 a and 17 c of the development body 17 are not bonded to each other and are erected so as to be swingable with the side on the bottom side as a base, and the development body 17 includes the side surfaces 17 a and 17 c. Is used in an unbonded state. For this reason, the internal volume inside the deployment body 17 can be changed by adjusting the standing angle of the side surfaces 17a and 17c. According to this, the variation in the dimension of the sealed package 7 to be stored (packaged by the sheet package 16 or the like) can be absorbed by adjusting the shape of the deployable body 17. For this reason, the sealed package 7 (packaged by the sheet package 16) can be easily stored in the developing body 17 without performing strict size control on the sealed package 7 (packaged by the sheet package 16). can do. Further, the outer shape can be adapted to the inner shape of the case body 13 by appropriately adjusting the shape of the development body 17. Therefore, if the deployment body 17 is used as a correction member that corrects the shape of the gusset bag 18 to approximate the inner shape of the case body 13, the gusset bag can be obtained without strict dimensional control with respect to the shape of the case body 13 and the deployment body 17. 18 can be easily approximated to the inner shape of the case body 13.

  The gusset bag 18 is a bag body which becomes a substantially rectangular parallelepiped autonomously when the inside is inflated, and has an upper surface opened in an initial state. The length of the gusset bag 18 in the longitudinal direction (the direction from the bottom surface 18c toward the opening 18a) is approximately twice the height (Z2) of the case body 13, and the sealed package 7 and the like are housed inside. The opening side of the four side surfaces 18b of the gusset bag 18 is overlapped so that the opening 18a can be closed. The length of the gusset bag 18 in the longitudinal direction may be a length that allows the open sides of the four side surfaces 18b of the gusset bag 18 to be overlapped with the sealed package 7 and the like stored therein. It is not limited to approximately twice the height (Z2) of 13.

  In the initial state (before insertion of the sealed package 7 or the like), the side face 18b1 on the left and right sides when viewed from the front is folded in a substantially “U” shape on the center side with the folding line 18d as a vertex ( A pair of opposing side surfaces 18b1 is a folded portion). The bottom surface 18c has a seal portion 18c1 formed by heat-sealing from one end to the other end in the width direction (a direction intersecting the longitudinal direction) as a boundary, one on the side 18b2 on the front side in front view, and the other Are flush with the side surface 18b2 on the rear side in the front view.

  When the deployment body 17 or the like is inserted into the gusset bag 18 from the initial state, the side surface 18b1 is expanded and expanded from the initial state due to the thickness of the deployment body 17 or the like, that is, the inside is expanded. When the side surface 18b1 is extended, the end portion on the bottom surface 18c side of the second side surface 18b1 is folded into a gable roof shape at the point where the folding line 18d and the seal portion 18c1 meet, and is folded to a part of the bottom surface 18c. Overlaid. Thereby, the side surface 18b1 is in a form of a substantially rectangular surface in a side view. Further, when the end portion of the side surface 18b1 is folded into a gable roof shape, the bottom surface 18c is developed in the front-rear direction around the seal portion 18c1, and is formed in a substantially rectangular surface shape. As a result, as shown in FIG. 11, the gusset bag 18 has a substantially rectangular parallelepiped shape including a side surface 18 b 1 that is substantially rectangular in side view and a bottom surface 18 c that is substantially rectangular, and has an open top surface.

  The gusset bag 18 is formed of a resin-made flexible film body that can be heat-sealed in the same manner as the bag body 12. For this reason, the sealing package 7 etc. can be sealed inside the gusset bag 18 by heat fusion by heat sealing.

  Next, a packing method for packing the sealed package 7 using the packing tool 20 of the sixth embodiment will be described. First, the sealed package 7 enclosing the recording head 1 is packaged by the sheet package 16 and sealed. The gusset bag 18 has a mode in which two rectangular sheet bodies are laminated by aligning the inner side surfaces of the cylindrical sheet body, and the edges on both sides (non-opening side) along the longitudinal direction are formed as folding lines 18d. Each opening is formed by linearly heat-sealing one opening from one end to the other end in the width direction. As a result, a seal portion 18c1 on the bottom surface 18c side is formed, and the side not heat-sealed becomes the opening 18a. Then, a part of the deployable body 17 (from the bottom surface side to a predetermined height) is inserted into the gusset bag 18 from the opening 18a (state shown in FIG. 11).

  In such a state, the sealed package 7 packaged in the sheet package 16 is set inside the development body 17. As described above, since the side surfaces 17a and 17c are not bonded, the upper surface of the deployable body 17 can be largely opened with respect to the sealed package 7 to be inserted. The sealed package 7 (packaged in) can be easily set.

  Subsequently, after inserting the gusset bag 18 into the case body 13 from the bottom surface 18c side, the sealed package 7 is inserted into the back of the gusset bag 18 together with the development body 17, and the bottom surface of the case body 13 via the gusset bag 18 A deployment body 17 containing the sealed package 7 is placed. Then, the folding line 18d is folded on the upper side of the deployed body 17, and the air in the gusset bag 18 is pushed out from the opening 18a, the four side surfaces 18b are overlapped to close the opening 18a side, and heat sealing is performed. The gusset bag 18 is sealed by heat sealing. Thereafter, the excess portion of the gusset bag 18 protruding outward from the upper surface of the case body 13 is folded and pushed into the case body 13, and the four lid members of the case body 13 in an opened state are folded inward to fold the case body 13. Block the top surface of.

  Thus, since the gusset bag 18 which becomes a self-supporting substantially rectangular parallelepiped is used for the bag which seals the sealing package 7, the external shape of the original bag before correction | amendment by the expansion body 17 is made into a substantially rectangular parallelepiped. That is, the original outer shape of the bag body and the inner shape of the case body 13 can be approximated in advance. When the original outer shape of the bag body and the inner shape of the case body 13 are close, the difference in shape of the bag body before and after correction by the correction member can be reduced. The greater the difference in shape before and after correction, the greater the slackness or deflection of the bag after correction. This slack or deflection becomes a factor of expansion of the bag body. In the sixth embodiment, since the gusset bag 18 is used for the bag body, it is possible to suppress the slack and the bending generated in the bag body after the correction by the correction member, and therefore, compared to the case of using another bag body. Further, the expansion of the bag body under a reduced pressure environment can be strictly regulated. In addition, although the expansion | deployment body 17 was formed by the four side surfaces 17a and 17c provided in a row by the bottom face and the bottom face, you may provide the upper surface which further faces a bottom face. The upper surface may be separate from the deploying body 17 and may be configured to be detachable. Also, the upper surface is connected to one end on the opening side of the side surfaces 17a and 17c of the deploying body. May be.

  As described above, according to the packaging packages 10, 100, 110, 120, 130, and 140, even when the recording head 1 is transported in a reduced pressure environment, a sealed space (bag) that includes the recording head 1. The atmospheric pressure in the body 12) can be maintained at the atmospheric pressure equivalent to that in the normal pressure environment. Therefore, the ink sealed in the recording head 1 does not leak out.

  The present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. It can be guessed.

  For example, in each of the above embodiments, the fluid sealed in the recording head 1 is ink, but the sealed fluid is not limited to ink, and may be other liquids such as a storage solution. Further, in each of the above embodiments, the sealed container to be packed is the recording head 1, but the packing package of the present invention can be applied to the packaging of various containers that enclose fluid other than the recording head 1, for example, The present invention may be applied to an ink cartridge filled with ink to be supplied to the recording head 1. The fluid is not limited to a liquid, but flows or flows out in a sealed container, and is a concept that includes a gas and a solid in addition to a liquid. Examples of the solid as the fluid include powder composed of fine particles such as toner.
